The Dodecaedro Traforato or Perforated Dodecahedron is a modular origami by Silvana Betti Mamino. Like most modular origami, the modules are pretty easy to fold. They are folded from a A4 sheet. Well, the A4 is actually cut into 4 rectangles horizontally. I felt A4 strips would be too big, so worked with A5 sheet cut into 4 rectangles. Worked perfectly well :) I used printer paper - 5 colours and 6 strips in each colour.
Folding printer paper wasn't that easy - 80 gsm paper requires more effort to fold than 60 gsm, doesn't it? Assembling for me, was the most challenging part. The reason was because of the colours. I wanted to ensure that there was some kind of uniformity in the assembly and after 3 attempts, I finally managed it I think.
The modules hold together without glue once fully assembled. But I didn't find it terribly stable, so if you will be moving it about, then a little glue helps. If you are assembling without glue, ensure you have a whole bunch of paper clips to hold the modules in place.
